title: Service Registry
---
Istio 维护了一个内部服务注册表 (service registry),它包含在服务网格中运行的一组[服务](/zh/docs/reference/glossary/#service)及其相应的[服务 endpoints](/zh/docs/reference/glossary/#service-endpoint)。Istio 使用服务注册表生成 [Envoy](/zh/docs/reference/glossary/#envoy) 配置。
Istio 不提供[服务发现](https://en.wikipedia.org/wiki/Service_discovery),尽管大多数服务都是通过 [Pilot](/zh/docs/reference/glossary/#pilot) adapter 自动加入到服务注册表里的而且这反映了底层平台Kubernetes、Consul、plain DNS的已发现的服务。还有就是可以使用 [`ServiceEntry`](/zh/docs/concepts/traffic-management/#service-entries) 配置手动进行注册。
